An input error occurs if a G code, to
of plane designation for changing the
compensation plane is programmed during
compensation.
Program circle cutting , and

cancel mode.
Circle cutting and helical
cutting incorporate tool radius compensat-
ing functions in themselves.

Tool radius compensation C is also possible on
circular interpolation by radius designation.
Subprogram M99) can be programmed in
compensation mode.
Compensation is applied to the projection to
the compensation plane designated by
G18 or G19 when simultaneous movement
along three axes (four
maximum) is pro-
grammed in compensation mode.

Advance reading of blocks is prohibited
when MOO,

given, and compensation is usually inter-

sation is secured by programming 1, J, K
in a dummy block immediately before MOO,

Up to 99 values can be stored in the
offset memory in total for the tool radius
compensation , together with the values for
other compensation.
Make designation by
a D code. The maximum programmable value
of tool radius compensation is 999 mm
(or 9999 inch) .
occurs if compensation is program-
med on a step less than the too! radius in
M96 mode.
Keep this in mind. Although
undersize cut with the G97 mode , it
is better than overcut with the M96 mode.
